Take the 200+ steps down from Oia for a swim that actually feels refreshing. Skip the donkey rides; your knees can handle the walk. Head left past the tavernas to find the trail leading to the massive red rock for cliff jumping. Most catamaran cruises depart from here, so it gets hectic by 2pm. Grab a table at Sunset Ammoudi for the lobster pasta if you're splurging, or just bring sneakers for the rocky trek.
